DOOR-BUMPER.

*0 I Specification of Letters Patent.

Application filed June 19, 1920. Serial No. 890,205.

To all whom it may concern Be it known that I, SETH ll. A'rwoon, a citizen of the United States, residing at Rockford, in the county of \Vinnebago and State of Illinois, have invented certain new and useful Improvements in Door-Bumpers, of which the following is a specification.

This invention relates in general to door bumpers, and while capable of application to various types of doors, is particularly adaptable for automobile doors.

One of the primary purposes of my present invention is to provide a door bumper of the character indicated, which can be economically manufactured and readily assembled.

Another object is to provide a bumper which per will form the door strip of the door casing. thereby obviating the necessity of the usual door strip with which car bodies are customarily equipped.

A further teature of my invention resides in the provision of a bumper, in which none of the metal is cut away, but on the contrary, all of the metal is retained in the bumper construction to add strength and rigidity to the structure, as ivell as to afiord provision for holding the bumper block in position. It will be manifest that losses in the manufacture of bumpers resulting from scrap material, are obviated by my improved construotion.

Various other objects and advantages 01 my invention will be readily appreciated as the same becomes better understood by reference to the following description when considered in connection with the accompanying drawin s.

Referring to t 1e drawings:

Figure 1 is a fragmentary perspective view'of an automobile body, equipped with my invention;

Fig. 2 is a through one of my improved bumpers; and

Figs. 3, 4 and 5 are detail perspective views of the bumier block, the channel shaped member and clamping plate respectively.

Referring to the drawings more in detail, rct'crcucc character 6 indicatcs generally the body of an automobile provided with the usual door casing 7. This body may be of any approved construction, but my invention is particularly adaptable for use in connoetimi with all metal bodies, which are being quite extensively manufactured.

transverse sectional view In the construction of both wood and metal bodies, it has heretofore been custom cry to rovide a door strip along the verticdl si e of the door casing, against which the door is adapted to close, rattling between the strip and the door being prevented by the interposition of rubber bumpers of various characters, My present invention contemplates the eliminationv of the ordinary door strip and the substitution therefonof a combined door strip and bumper, so that the whole structure can be economically manufactured and quickly andeasily assembled and connected to the car body.

With this desideratum in view, I have provided a member 8 of channel shaped construction, which is shaped to conform to the contour of the door casing. In the body shown for purposes of illustration, the vertical wall of the casing is substantially straight, but in many bodies, it is more or less curved, particularly near the lower end thereof and in the application of my invention to such a body, the member 8 is similarly curved so that it will conform to and tit snugly against. the face of the door casing.

Intermediate its ends, preferably at two points. the outer flange of the member 8 is severed transversely and also for a short dis tance at each side of this cut along'its juncture with the transverse web of the channel member. These severed tongues 10 are then bent inwardly so as to be disposed in a.- proximately parallel relation transverse y of the channel. It. will be observed that the formation of these guides by bending inwardly the-metal of the flange 9, provides an open ended guide-way extending transversely of the channel member without cutting out and scrapping any of the metal, so that losses incident to scrap metal are ob viated.

\V'ithin explains-(1,1 dispose a of resilient material such as rubber. block throughout its body portion, is slightly each guideway formed as above bumper block 11,m ade narrower than the depth of the flanges'of the channel sha )ed member and at its outer end, it is provided with a lateral extension 12 adapted to project outwardly beyond the face of the transverse web of the channel shaped strip, as will be evident from Fig. 2. When the block has been positioned in the channel. it is held therein by a screw inserted into the channel through the tra verse Web thereof and threadedly engaged at This 1 Patented Sept. 21, 1920.

its inner end with a clamping plate 14 which is disposed agail'ist the inner lace of the bloek 11. To acconnnodate this screw, the block 11 is provided with :z transverse opening 1-? through which the w w: trod, and preferably, this opening in i slot which will permit longitudinal adjustment of the-bumper bloelt when the srrew is loosened, thereby permitting the block to be adjusted to take up for wear The door of the body is indicated generally by i'i *'i i=!'i"!it3(,: character 16 and from Fig. 2, it will be observed that a flange 17 formed on the outer edge of the door, overlaps the bumper l!l :('l( and provides the abutment surface, hit-h prevents rattling.

It will be observed that the channel shap d member #5 serves the purpose of the ordinary door strip, and in addition thereto, (sari h'h the bumper blocks which. can be tlttilp itf l 'o {be strip before the strip is connected to the )ody. The strip having been t'orintd to provide the guideways f r the lnunpei' blocks, as explained, the blocks are Hrrixi'ivx' in positiomthe plates bl are disposed aga msi iii iv the inner faces of the blocks whereupon l. insertionof the screws 13 eonnerts the bioe to the strip and holds them in p-' siti-1 :i 5? that the strip carrying the him-ks can then be attached to the door frame by sore-iv. lb or other preferred fastening means. After the bumpers have been in use for soua thin and have become compressed or worn down, they may be adjusted to insure the requisite fit between the door and the easing by sin ply loosening the screws 13 and adjusting the blocks to any desired position.

It will be observed that this construction is strong and durable, that it can be economieally nn'uiufactured without waste of material, that it can be easily assembled and applied to a door easing, that it eliminates oform of a.

iln ordinary door strip, and that it elieetually prevents rattling oi' the doors. 'hile I have shown and described :1 preferred embodiment of my invention, it should be understood that it is capable of considerable nuidilication in its details without departing from the spirit of the invention, as defined in the following claims.

I claim:

1. A. door bumper, eomprising a channel shaped member having one flange out and bent inwardly on opposite sides of said out to provide a pair of transversely extending guides within the rhanuel, a resilient bumper block positioned between said guides and projecting outwardly between the plane of said flange, a plate disposed against the innor l'ai-e of said block, and means for clam iug said block between said plate and the transverse web of said member.

2. in a bumper for automobile doors, the winbination of a channel shaped member formed to fit and adapted for attachment to an auton'lobile door casing to provide the oor st rip therefor, said. 11181111301 having a ortion of one flange bent inwardly to proi e transverse guides, a resilient bumper blorl; positioned between said guides, and neans for adjustably holding said block in po-izion on said member.

.i. ii bumper for automobile doors, coma channel shaped member formed to pr mg lit :2 door casing and adapted to be attached iin'l'vlu to provide the door strip, the outer ildllii'i oi' said strip being out and bent in wardlg' to provide guides extending transversely oi the channel, a resilient bumper blorlt di posed in said channel between said guides and projecting outwardly beyond the plane of the face of said flange, and means i or clamping: aid block in )osition.
